It loks the same in this picture as it did in the first.....keep an eye on it as you are doing and speak to the vet if there are any changes. For example heat, pain, redness, swelling, discharge and smell are all indicators of infection. Saying that she's just had an op so some swelling and pinkness should be expected at first. Keep her confined as you already are, give her lots of love and snuggles for being a brave baby and try not to worry too much......and if your still worried you should take her to the vet for peace of mind.
Mums always worry too much.thats what we're here for xx
